Airborne radiotracers

Natural radionuclides including 222Rn, 220Rn, 210Pb, 7Be have been used to examine a large variety of relevant atmospheric processes. Routine measurements of these naturally occurring radionuclides in Antarctica. Zucchelli Station and at Campo Icaro, help to understand the atmospheric composition and its variations. 222Rn, 220Rn are measured in situ with a dedicated low level alpha spectrometer working in continuous mode, with a time resolution of two hours. 210Pb and 7Be are measured on aerosol filters sampled with a high volume device every three days. Measurements are carried out in Bologna using HPGe spectrometers.
